I think sensitization and creating more awareness should be the solution because some market woman don't even want to hear anything about online business talk more of hearing of Bitcoin, due to some ponzi schemes they think there is no genuine online business, so creating more awareness about Bitcoin should be the solution.
Agree with you one good solutions is creating awareness in our Nigerian society because truth be told the ordinary market women may not even be aware of what is called Bitcoin not to talk about anything online and even the once that are aware is afraid, because of the wrong messages that has been passed down by ignorant people who lost money in crypto due to lack of sufficient knowledge about crypto before entering so one good way for business owners to start accepting bitcoin as means of payment is via creating awareness.
This is one of the reason why it is not everyone who will invest on Bitcoin or use Bitcoin for their businesses. The reason why is because it is not everybody that understands how to use it. The local market people that sells things in street will need to learn about it before they can use it not they will lose their Bitcoin to either an address they do not know or they lose their seed phrase. We do not need to make awareness for people to know Bitcoin, with the good news people are talking about Bitcoin they will know it is a legit means of investment.
